Beta molecular sieve is very beneficial to petroleum hydrodewaxing and pour point reduction. The pore characteristics of Beta molecular sieves make it highly selective for breaking chain hydrocarbons in the cracking reaction. During the cracking process of petroleum hydrocarbons, cracking products with high carbon numbers and low pouring points can be obtained. Therefore, Beta molecular sieves are used as a base based on petroleum hydrocarbons. Refining catalysts for raw materials have good industrial application prospects. The pouring point of diesel produced by it is much lower, and it is a new type of hydrocracking catalyst for producing low pouring point diesel and medium oil type. Adding modified Beta molecular sieve to FCC catalyst can reduce the olefin content of catalytic cracking, and at the same time, it can appropriately increase the octane number, reduce the condensation rate of medium-grade oil (diesel), etc. For disproportionation reactions and alkylation reactions such as toluene, trimethylbenzene and C9, Beta molecular sieve has stability and high selectivity.
